I just wan quote you to make the page longer lemon10: to play a vital role as a conducting support in providing an effective electron pathway to the NiOx shell, resulting in an enhanced OER activity. Following this finding, Liang et al. reported a NiFeP–amorphous NiFe–OH heterostructure (Fig. 4a), which was realized by hydrothermal growth of NiFe–OH on Ni foam and subsequent phosphorization conversion, followed by electrodeposition of amorphous NiFe–OH on preformed NiFeP NSs.69 Remarkably, the as-prepared NiFeP/a-NiFe–OH only required an overpotential of 199 mV at 10 mA cm2 and could attain 300 mA cm2 at a very low overpotential of 258 mV, significantly outperforming NiFeP and NiFe LDH pre-catalysts with similar morphologies and mass loadings (Fig. 4b), which demonstrated the promotional effect of heterostructuring. (ii) TMO/TMP heterostructures. Compared to TMPs, TMOs are usually wide band gap semiconductors or insulators having much higher electrical resistance. Therefore, unlike TMP/TMO, improved charge transfer does not prevail in TMO/TMP heterostructures, and the enhanced OER activity usually arises from the electronic interaction between the TMO and TMP components. Hao et al. reported the fabrication of NiO@Ni–P core–shell hybrid NS arrays (Fig. 4c) and found that the hybrid NiO@Ni–P arrays only required overpotentials of 292 and 350 mV at 10 and 100 mA cm2 , respectively, dramatically lower than those of NiO and Ni–P NS arrays with similar morphologies and catalyst loadings (Fig. 4d).70 Their DFT calculations indicated that the overpotential of the rate-limiting step on the model NiO/Ni–P interface is smaller than that of NiO or Ni–P, which reasonably explains the observed better OER activity of the NiO@Ni–P hybrid, corroborating that coupling of NiO and Ni–P leads to enhanced OER performance. In addition, a CuO@CoP heterostructured electrode was also recently reported.71 XPS investigations confirmed the electronic interaction between CuO and CoP, which was used to explain its enhanced OER performance. However, given that CuO is a photoactive semiconductor, whether the photoelectrochemical effect comes into play in the CuO@CoP hybrid remains unclear and deserves further investigation. (iii) TMP/TMP heterostructures. TMP/TMP heterostructures consisting of different TM species in each TMP have been developed recently aiming to achieve improved OER performance. For example, Liu et al. reported the fabrication of Ni2P NPs grown on Fe2P NSs (M-Ni2P/Fe2P–O) using hydrothermal synthesis of metal hydroxide precursors followed by conventional phosphorization treatment.72 Notably, the M-Ni2P/Fe2P–O showed an extremely low Z10 of 179 mV and a small Tafel slope of 42.7 mV dec1 , and could sustain at 40 mA cm2 for 120 h without significant degradation. The researchers attributed the high OER activity to the synergistic effects of Ni2P/Fe2P interfaces, namely, the active surface layers and metallic phosphide bulk. The oxidized surface acted as a proton-coupled electron transfer mediator, expediting the kinetics of the OER; meanwhile, doped oxyhydroxides could accelerate the formation of O–O bonds and lower the activation barrier for the OER. Besides, TMP/TMP heterostructures comprising the same TMP but different polymorphs were also demonstrated to show a promotional effect on the OER. For instance, Li et al. recently prepared polycrystalline CoP/CoP2 heterostructures and found that the polycrystalline CoP/CoP2 showed better OER performance than phase-pure CoP because of the presence of sufficient active sites and Co(II) and Co(IV) species in the heterostructure.73 (iv) TMP/TMS and TMP/TMX (X = N, C, etc.) heterostructures. In addition to TMP/TMO and TMP/TMP, transition metal sulfide (TMS), nitride (TMN) and carbide (TMC) were also reported to composite with TMP for use as heterostructured pre-catalysts toward the OER. Ni2P–Ni3S2 heterostructures were reported recently for catalyzing the OER with a small Z10 of 210 mV.74 DFT calculations showed that strong coupling interactions exist between Ni2P and Ni3S2, which result in a lower H2O adsorption energy value as compared to pure Ni2P or Ni3S2; meanwhile, the denisty of states (DOS) of Ni2P–Ni3S2 is in the metallic state with an enhanced carrier density near the Fermi level with respect to pure Ni2P and Ni3S2, both of which contribute to the enhanced OER performance. As far as TMP/TMN heterostructures are concerned, Sun et al. recently reported the synthesis of Ni2P/CoN hybridized with N-doped porous carbon polyhedrons (PCP) using a MOF-directed approach.75 Ni2P NPs were anchored on CoN–PCP by thermal decomposition of a mixture of NaH2PO2 and NiCl2 in an inert atmosphere, and the resulting Ni2P/CoN–PCP showed a high surface area of 712 m2 g1 , which was supposed to result from the high degree of dispersion of active sites and would promote mass transport during the eletrocatalytic processes. Besides, CoP–Mo2C heterostructured pre-catalysts were obtained by a similar MOF-directed synthesis.76 Notably, the CoP–Mo2C pre-catalyst was Fig. 4 (a1) SEM and (a2) high-resolution TEM images of NiFeP/a-NiFe–OH hierarchical nanostructures.

This journal is © The Royal Society of Chemistry 2019 not only active for the OER in alkaline media with an Z10 of 265 mV, but also capable of catalyzing the OER in 0.5 M H2SO4 showing an impressive Z10 value of only 330 mV. Moreover, CoP–Mo2C also exhibited outstanding catalytic stability for the OER in acidic electrolyte, rendering it one of the best PGM-free acid-stable OER catalysts reported so far. (v) TMP/C heterostructures. Compositing catalysts with carbon has been broadly used as an effective strategy to improve their catalytic performance. In this respect, numerous works on TMP/C hybrids have been reported to be used to catalyze the OER. There are three different types of TMP/C heterostructures, including (1) TMP NPs supported on carbon-based materials;77 (2) carbon nanostructures, typically nanodots (NDs), supported on TMPs;78 and (3) TMPs embedded or encapsulated in carbon or doped-carbon.79 In almost all cases, it is proposed that carbon makes a positive contribution to the OER performance, by enabling efficient charge transfer and offering abundant surface sites for catalyst nucleation by virture of surface chemical affinity that could have an excellent anchoring effect to prevent the catalysts from detachment. For example, Liang et al. investigated the effect of CNTs heterostructured with Co0.7Fe0.3P on the OER activity, and found that Co0.7Fe0.3P/CNT showed better activity than unsupported Co0.7Fe0.3P.77 Hou et al. reported Co–Ni–P NSs embedded with graphene dots (GDs) and demonstrated that the charge transfer properties were indeed improved after incorporating GDs on Co–Ni–P NSs.80 Even if GDs facilitate charge transport, the authors found that a high density of GDs dispersed on Co–Ni–P NSs would lead to a decrease in OER activity. This is due likely to the increased resistance and the over-occupancy of GDs on the catalytically active surface. A similar phenonmenon was also observed in the CoP/C ND composite.78 For TMPs embedded or encapsulated in carbon, although the positive effect of carbon encapsulation on the enhancement of the OER has been repetitively reported, it remains unclear how the OER microscopically takes place on the catalysts. The prevailing model used to interpret the OER taking place on transition metal compounds is based on the assumption that there are exposed metal sites on the surfaces of the catalysts. While electron conduction may still occur upon carbon encapsulation, how the OH groups or water molecules penetrate the carbon layer, how and where the O* and *OOH species form, and how the evolved O2 gas escapes from the intimately contacted TMP/C interface have not been understood at all. Wang et al. recently thoroughly investigated the strengthened synergistic effect (SSE) between MxPy (M = Co, Ni, Cu) and the carbon layer in an MxPy@C peapod structure on the OER activity.81 According to their observation, during the OER, MxPy would be partially oxidized, and the formed oxide served as catalytically active sites, while the MxPy having tight atomic contact with carbon would be protected from oxidation, and thus able to offer fast charge transfer. However, why there was some MxPy being oxidized and the others not has not been elucidated. More importantly, unlike the HER and oxygen reduction reaction (ORR), the OER proceeds under strong oxidative conditions under which carbon tends to be oxidized,82 forming carboxylic and phenolic groups and even surface oxides, which would lead to a degradation. So far, no attention has been paid to the influence of carbon oxidation on the long-term OER perforamnce of TMP/C heterostructured pre-catalysts, and investigations in this respect need to be carried out in the future. Transition metal chalcogenide based OER pre-catalysts Transition metal sulfides Transition metal sulfides (TMSs) have attracted intensive research attention in electrocatalysis and batteries, due to their excellent electrical conductivity, tunable metal–sulfur coordination environment and remarkable electronic and chemical properties.83 For example, under-coordinated Mo–S sites along the edges of MoS2 possess high chemisorption capability for hydrogen, thereby being able to lead to high catalytic activity for the HER.84 Recently, various TMSs have been reported to catalyze the OER and to directly couple TMS-based HER catalysts for overall water splitting,11 given that the combination of the same sulfide electrodes will simplify the design and construction of water electrolyzers and potentially lower production cost. TMS-based OER pre-catalysts reported so far primarily include cobalt sulfide, nickel sulfide, iron sulfide, copper sulfide, molybdenum sulfide, tungsten sulfide and their composites.5,11 The complex coordination environments between TM and S render various TM/S stoichiometric compositions. For example, diverse cobalt sulfide pre-catalysts have been studied for the OER, including Co3S4, Co9S8, CoS2, and CoS.85,86 These cobalt sulfide materials can be synthesized by hydrothermal/ solvothermal processing, electrodepo |

AutoReportNG: Lagos State Governor, Mr Babajide Sanwo-Olu, on Wednesday restated his commitment to collaborate with residents and people of the state for successful implementation of his administration’s policies and programmes.
The governor, who said this when he hosted Muslim faithful in Lagos House, Alausa, Ikeja to mark 2019 Eid-el-Fitri informed the gathering that his government will soon release emergency hotlines to the public to call the Lagos State Public Works for immediate fixing of potholes and roads that need urgent repairs.
“Let us have continuous collaborative engagements. We will continue to ask you to work with us. We would be calling on you at different times.”
“Our Public Works Corporation would come out and start fixing all the potholes on our roads. We would soon publish the numbers that people would be calling to notify us of wherever there are potholes in the state”, Governor Sanwo-Olu stated.

He expressed happiness as he joined Muslim brothers and sisters to celebrate the end of Ramadan after a long period of spiritual cleansing and self discipline, urging them to pray for the success of his administration.
According to him, “I am happy and pleased to join our Muslim brothers and sisters in this glorious celebration of Eid-el-fitri. A long stretch of fasting like this is not the easiest thing. It takes special grace and personal discipline, to go through the religious obligation.
“Continue to pray for the success of our administration and our prayers is that we all witness next year in good health and progress”.
